The Baltimore Sun reported on Friday the shooting was recorded on a video camera by a third person.

In that video, Mitchell brags that he is about to take a "deuce deuce in the chest" - a shot from a .22-caliber bullet - before Ramiro, who is seen standing in front of Mitchell, fired the handgun once. He struck Mitchell just above the vest, the newspaper said.

Police would not comment on specific evidence.

Ramiro drove Mitchell to a hospital where he was pronounced dead, according to police. Ramiro is being held on homicide charges and weapons violations.
